So I know I shouldn't of tested early but I tested at 7dpo and I got a faint line on a Amazon cheapy. Next day I tested it was gone and I had a negative test. I'm now 11dpo and I have AWFUL nausea, lower back pain and I can't stop crying because I'm so hormonal. Could this all be because of a chemical pregnancy or could the faint line I had be a evap line?

Here is the 7dpo line
